Pediatric Allogeneic Hematopoietic Stem Cell Transplantation Including Matched Sibling and Alternate Donor Transplants – Adaptations and Outcomes From a Tertiary Care Government Institute in India

To report the outcomes of pediatric patients who underwent allogeneic hematopoietic stem cell transplant (HSCT) in single rooms without high-efficiency particulate air (HEPA) filters, laminar air flow or positive pressure at our centre and discuss the adaptations of a high-volume government centre.

Data of the first 20 children who underwent allogeneic HSCT between May 2019 and July 2023 in adaptive settings were reviewed retrospectively. All patients were managed in in single rooms without HEPA filters, positive pressure or laminar air flow. Supportive care in the form of antimicrobial prophylaxis, veno-occlusive disease prophylaxis, anti-epileptics (with busulfan) and irradiated blood products were provided. Trained manpower including multi-specialty consultations were readily available. All complications including infections were managed as per standard guidelines.

The median (range) of children included was 6 (1–20) years. For eight patients we used alternate donors. The mean (SD) time to neutrophil and platelet engraftment were 17.0 (8.07) days and 18.8 (10.1) days, respectively. The mean (SD) time to discharge from the hospital was 30.9 (10.04) days. There were no deaths within 30 days. Six children each developed acute and chronic graft-versus-host disease (GVHD). The overall survival at a median follow-up of 292 days was 70% (n = 14).

With certain adaptations in the existing infrastructure in resource-limited settings, allogeneic HSCT can be performed with good outcomes, provided experienced, dedicated and adequate personnel, comprehensive supportive care, multidisciplinary consultative support and isolation are provided.
